vdiag 18, 1C, 20:
If the additional heater no. 1 relay does not operate when running command AC063:
Check the additional heater no. 1 relay mounting.
Check the engine management computer connectors.
Repair if necessary.
if the fault is still present, check as follows that this relay is controlled by the engine management computer:
Disconnect the additional heater no. 1 relay, fit a 50 Ω < X < 100 Ω resistor on the relay mounting in place of the
coil, and connect a voltmeter as follows:
Positive terminal to the +12 V battery.
Negative terminal to connection 3JA of component 597.
Clear the fault and actuate the relay using command AC063.
If the voltmeter shows the battery voltage (two, 2-second ON-OFF cycles), replace the additional heater no. 1
relay.
If the voltmeter does not show the battery voltage (two, 2-second ON-OFF cycles), contact the Techline.
If the additional heater no. 1 relay is supplied by command AC063, but there is still a fault with the passenger
compartment heating and demisting, check the following using a wiring diagram:
– the conformity of the thermoplunger maxi-fuse,
–+12V battery on connection 3FB of component 597.
– the conformity of the additional heater no. 1 relay,
– the continuity between connection 3JB of component 597 and connection 3JB of component 898,
– the conformity of the thermoplunger resistance: 0.40 Ω < X < 0.50 Ω at 20°C,
– the presence of earth at the water chamber (thermoplunger mounting).
Also check the level of the cooling circuit and that there are no leaks.
Carry out the necessary repairs.

If the additional heater no. 2 relay does not operate when running command AC064,
check the additional heater no. 2 relay mounting,
check the connectors on the engine management computer.
Repair if necessary.
if the fault is still present, check as follows that this relay is controlled by the engine management computer:
Disconnect the additional heater no. 2 relay, fit a 50 Ω < X < 100 Ω resistor on the mounting in place of the coil,
and connect a voltmeter as follows:
Positive terminal to the +12 V battery.
Negative terminal to connection 3JAA of component 597.
Clear the fault and actuate the relay via command AC064.
If the voltmeter shows the battery voltage (two 2-second ON-OFF cycles), replace the additional heater 1 relay.
If the voltmeter does not show the battery voltage (two 2 second ON-OFF cycles), contact the Techline.
If the additional heater no. 2 relay is supplied by command AC064, but there is still a fault with the passenger
compartment heating and demisting, use the wiring diagram to check the following:
– the conformity of the thermoplunger maxi-fuse,
–+12V battery on connection BP91 of component 597,
– the conformity of the additional heater no. 2 relay,
– the continuity of connection 3JAD between components 597 and 1072.
– the conformity of the thermoplunger resistance: 0.40 Ω < X < 0.50 Ω at 20°C,
– the presence of earth at the water chamber (thermoplunger mounting).
Also check the level of the cooling circuit and that there are no leaks.
Carry out the necessary repairs.

Fault finding – Fault Finding Chart
ALP 1 No dialogue with engine management computer
Try to establish dialogue with a computer on another vehicle to check that the diagnostic tool is not faulty.
Check the battery voltage and carry out the operations necessary to obtain the correct voltage
(9.5V If the tool is not at fault, and dialogue cannot be established with any other computer on the same vehicle, the
cause could be a faulty computer interfering on the multiplex network.
disconnect the engine management computer.
try to establish dialogue with another computer.
if the fault is still present, reconnect the computer and proceed by elimination by successively disconnecting all
the following computers (according to wiring diagram and equipment): air conditioning, airbag, abs and esp, uch,
instrument panel, central communication unit, proximity sensor.
try to establish a dialogue between each disconnection:
if, after a disconnection, you manage to establish dialogue, perform the fault finding procedure for the relevant
computer.
Carry out a fault finding procedure on the multiplex network using the diagnostic tool.
Check for the injection fuses on the protection and switching unit and/or in the engine fuse box and check their
condition.
Check the connection of the computer connectors and the condition of its connections.
Check the injection computer earths (quality, oxidation, tightness of earth bolts on the battery terminal).
Check that the supply to the computer is correct:
Earth on connections NT (Laguna II) or N (Scénic II and Mégane II) of component 120.
+ after ignition feed on connection AP29 (Laguna II) or AP15 (Scénic II and Mégane II) of component 120.
Check that the power supply to the diagnostic socket is correct:
– + before ignition feed on connection BP32 (Scénic II and Mégane II) or BCP4 (Laguna II) of component
225.
– + after ignition feed on connection AP43 (Scénic II and Mégane II) or AP10 (Laguna II) of component
225.
– Earth on connections MAN and NAM (Scénic II and Mégane II) or MA and NAP (Laguna II) of component
225.
If dialogue has still not been established after these checks, contact the techline.
AFTER REPAIRCarry out a road test followed by a complete check with the diagnostic tool.
